Thanks,Good Topic!
Like the way you presented your argument - Someone had a great display aquarium but you thought the frag racks detracted from the beauty of the presentation. You politely asked other reefers to help you understand.
Enjoy the discussion and the responses!
Myself, I have a frag rack in my aquarium because my corals are over growing and I need someplace to put them while I offer them to other reefers.
I envisioned this going very differently. Probably wouldn't have posted it if I had foreseen.
